SSL2109 系列 Green Chip 控制器 用于LED 照明 - SOIC-8

The is a compact non-dimmable Driver IC for driving strings of LEDs or high-voltage LED modules from a rectified mains supply. The IC is supplementary to the SSL21081/SSL21083 series but without an internal switch. The IC has been designed to start up directly from the HV supply by an internal high-voltage current source. Thereafter, the dV/dt supply is used with capacitive coupling from the drain or any other auxiliary supply. This functionality provides full flexibility in the application design. An internal clamp limits the supply voltage. The IC provides accurate output current control to within 5% LED current accuracy. The IC can be operated using Pulse-Width Modulation PWM current regulation and has many protection features including easy LED temperature feedback.
